Based on the number of games against current all-class top-25 opponents and the average rank of these opponents, I would say the following girls’ teams have the toughest schedules, in order of schedule strength:
Team --- # Games v Top-25 --- Avg Rank of Top-25 Opp. --- Strength Rating
==================================================
Byrnes --- 11 --- 9.18 --- 1.198
Irmo --- 12 --- 11.50 --- 1.043
Chapin --- 9 --- 10.30 --- 0.971
Summerville --- 4 --- 4.25 --- 0.941
Dutch Fork --- 12 --- 12.92 --- 0.929
Spartanburg --- 10 --- 10.80 --- 0.926
Eastside --- 7 --- 07.57 --- 0.925
NOTE: The Strength Rating is the product of the number of games versus top-25 teams times the inverse of the average ranking of these teams.
Ie. StrengthRating = #games X (1 / avg-rank)
